Animate UIView/NSView with 25+ timing functions. (Bounce, elastic, exponential, etc.)
Allows you to animate views in your app in the way you're familiar with (e.g. [UIView animateWithDuration:animations:]) but adds 25+ easing functions (from jQuery) to make your animations more visceral.
Advantages:
- Methods very similar to Apple's API.
- No Swizzling.
- No need to mess with keypaths, just change the properties on UIView and you're golden.
- Proper transform matrix interpolation, so rotations look correct.
- Install with cocoapods.
- Category methods prefixed.
In your Podfile, add this line:
pod "MTAnimation"
Then add the import:
// Same import for both iOS/OSX
#import <UIView+MTAnimation.h>
- Clone the repo (or download the zip) and run the iPad demo app to play around.
-
Download and run a developer signed Mac Example
-
Clone the repo (or download the zip) and build & run the mac app yourself.
Similar to the UIKits animation methods but you must supply an array of all the views you will be animating and an easing function.
[UIView mt_animateWithViews:@[view]
duration:0.25
timingFunction:kMTEaseOutBack
animations:^{
CGRect r = _logoImageView.frame;
r.origin.x = 50;
_logoImageView.frame = r;
}];You can animate:
UIView/NSView - frame
UIView/NSView - bounds
UIView - center
UIView/NSView - alpha
UIView - transform (CGAffineTransform)
CALayer - transform (CATransform3D)You can cut an animation into parts (using the range param). You might use this to swap the view half way through a flip animation:
_logoImageView.image = [UIImage imageNamed:@"logo"];
[UIView mt_animateWithViews:[view mt_allSubviews]
duration:0.25
delay:0
timingFunction:kMTEaseOutBack
range:MTMakeAnimationRange(0, 0.135)
options:0
animations:^{
CGFloat radians = mt_degreesToRadians(_endRotation);
_logoImageView.layer.transform = CATransform3DMakeRotation(radians, 0, 1, 0);
} completion:^{
_logoImageView.image = [UIImage imageNamed:@"logo-flip"];
[UIView mt_animateWithWithViews:[view mt_allSubviews]
duration:0.25
delay:0
timingFunction:kMTEaseOutBack
range:MTMakeAnimationRange(0.135, 1)
options:0
animations:^{
CGFloat radians = mt_degreesToRadians(_endRotation);
_logoImageView.layer.transform = CATransform3DMakeRotation(radians, 0, 1, 0);
} completion:^{
}];
}];This code will animate until the image is sideways, then swap out the image view's image and continue the animation so it looks like it has a backside.
- The view you animate must be layer backed. See
[NSView setWantsLayer:].
I have TODO: comments on stuff I need some help with, so feel free.
